As we shift from user experience to agent experience, the entire way we design, operate, and evaluate our products must be rethought. The first step is to understand how agents use products through MCPs and CLIs, the exact same way we used to understand how users interacted with UIs. Armature automates agent workflow testing. Connect your MCP, CLI and ChatGPT apps and let Armature discover the workflows agents actually run and continuously test them across every harness (Claude Code, Codex, Openclaw, etc.) and frontier model.
